ABSTRACT: A 65-year-old man with effort angina pectoris underwent percutaneous coronary intervention of the proximal right coronary artery. The lesion was dilated with a bare-metal stent under wire protection of the conus branch (CB). However, the jailed CB was occluded. Electrocardiogram with conventional precordial leads (V(1) through V(6)) accompanied with the supplementary leads (V(1) through V(6)) positioned 1 intercostal space higher showed marked ST elevation in V(1) through V(3) that was more prominent in V(1) through V(3). The 64-multidetector-row computed tomographic coronary angiography showed recanalization of the CB located just in the center of the V(1), V(2), V(1), and V(2) electrodes.
